34 | * Surface is a subclass of {@link Primitive} and is the basis for 2-dimensional geometry.

|
37 | * <p>
|
||
38 | * The orientation of a surface chooses an "up" direction through the choice of the upward normal,
|
||
39 | * which, if the surface is not a cycle, is the side of the surface from which the exterior boundary
|
||
40 | * appears counterclockwise. Reversal of the surface orientation reverses the curve orientation of
|
||
41 | * each boundary component, and interchanges the conceptual "up" and "down" direction of the surface.
|
||
42 | * </p>
|
||
43 | * <p>
|
||
44 | * If the surface is the boundary of a solid, the "up" direction is usually outward.
|
||
45 | * For closed surfaces, which have no boundary, the up direction is that of the surface patches,
|
||
46 | * which must be consistent with one another.
